For a decade, the classic Han River picnic has had a fixed menu: fried chicken, instant noodles cooked in a machine by the water, and a convenience-store beer. This autumn that menu has a challenger. On cool evenings at Yeouido Hangang Park and Nodeul Island, groups of friends and couples are unfolding picnic mats and opening plastic trays of fresh raw fish.
Koreans have a name for it: 회크닉 (hwe-nic), a blend of 회 (hoe, raw fish or sashimi) and 피크닉 (picnic). It is one of the most-searched food outings in Korea right now, and unlike a sold-out snack, it is something any visitor can actually do this week.
A note on sources: figures below come from Korean press and city-government coverage between September and October 2026, plus a Korea JoongAng Daily feature. Search-volume figures vary by tracking tool, some prices come from older blog posts, and I could not independently verify market conditions on the day. Treat everything as a snapshot and check with the stall before you pay.

What Is Hwe-nic?
Hwe-nic means buying ready-to-eat sashimi, usually at Noryangjin Fish Market, taking it to a riverside park, and eating it on a picnic mat. The classic version looks like this:
- Sashimi packed to go, often a mixed platter of seasonal fish.
- Sauces, wasabi and sliced garlic and chilli in small containers.
- A drink, and very often a cup of 한강라면 (Hangang ramyeon), the instant noodles cooked in the park’s vending machines.
- A mat, a view, and a phone for the photos.
Korean press describes it as a new twist on a very old Han River habit rather than a brand-new invention. What changed is the menu. Seafood is increasingly sharing mat space with fried chicken and ramyeon, according to the Korea JoongAng Daily, which reported that buyers are typically friends or couples and that a vendor credited Instagram Reels with popularising it. The same vendor suggested that many young people now find the standard chicken picnic a little dull.
Why It Took Off This Autumn
Three things seem to be driving it.
1. Social media. Reels and short videos of glossy sashimi trays against a Han River sunset are made for the feed. Korean reporting describes the trend as something that spread through SNS first and then showed up in the market.
2. The numbers. A September economic-press report said Google Trends interest in 회크닉 jumped sharply in September, by more than 5,000% against the same period a year earlier. On Naver Datalab, interest hit its one-year peak on 29 September. One analytics tracker put monthly Naver searches at around 5,500 over the latest month, against roughly 50 in July. These are small absolute numbers next to a big viral snack, so read them as “very fast growth from a very low base” rather than “everyone in Seoul is doing this”.
3. Experience spending. Korean commentators call it 경험 소비 (experience consumption): spending a modest amount on something that feels special and is easy to share. Compared with a restaurant sashimi set, a takeaway tray eaten outdoors is cheaper, and the setting does the rest of the work.
The weather matters too. Raw fish on a mat is a poor idea on a hot day, so the trend only really opens up once evenings cool, which is exactly where we are now.
How to Do Hwe-nic: Step by Step
1. Choose your fish at Noryangjin
Noryangjin Fish Market is the traditional source. Many stalls will slice fish to order and pack it for takeaway. Some Korean reports say takeaway customers now make up the large majority of sales at busy times, and one stall owner described waits of over an hour. Expect a queue on a nice evening or weekend.
If you want to understand what a market-sourced meal can be at the high end, our Noryangjin omakase review covers a sit-down alternative.
2. Ask for takeaway packaging, sauces and ice
Ask for 포장 (po-jang, takeaway). A blog guide to the market says many stalls will pack sauces separately, which helps keep the fish fresh, and that ice packs are often provided free. Korean food-safety advice is consistent: on warm or sunny days, keep raw fish cold with ice packs and do not leave it sitting out.
Some stalls have started offering pickup services and group purchases aimed at Han River picnickers, so you can collect without browsing the market floor. Ask your stall or check its social account.
3. Pick a spot
Korean coverage most often mentions two destinations close to Noryangjin:
- Yeouido Hangang Park: wide lawns, the most famous skyline view, and convenience stores and ramyeon machines nearby.
- Nodeul Island (노들섬): a small island in the river with grass areas and a calmer, more design-conscious feel.
4. Add the side dishes
Pick up drinks, rice or a cup of Hangang ramyeon from the park’s convenience stores. Having something hot beside raw fish is part of the ritual for many people.
5. Clean up properly
This is the part Korea is currently arguing about, so read the next section.
What It Costs
Prices change with season and fish. Here is what the sources say:
| Item | Reported price |
|---|---|
| Seasonal sashimi platter for two (JoongAng Daily, vendor quote) | From around ₩65,000 |
| Takeaway packaging at Noryangjin (older blog guide) | Roughly ₩500 to ₩1,000 per plate |
| Prep fee if you buy whole fish and have it cut (older blog guide) | Roughly ₩3,000 to ₩5,000 per person |
| Seating fee if you eat at the market (older blog guide) | Around ₩2,000 per person |
Taking it away avoids the seating charge. Fish prices fluctuate daily, so ask the price before the fish is cut and confirm the total before you pay. A reasonable budget for two people with drinks and a cup of ramyeon each is roughly ₩70,000 to ₩90,000, which is our own estimate rather than a published figure.
Where to Eat It
- Yeouido Hangang Park is the easiest choice for first-timers, with the most facilities and the biggest crowds.
- Nodeul Island is quieter, and a good fit if you prefer a calmer view.
- Anywhere with a bin and shade. If a park looks crowded, choose another stretch of the riverside. For more Han River ideas, see our guides to Han River paddleboarding, the Han River running club scene and mul-meong Han River cafes.
Follow the posted park rules about alcohol, cooking and where you may sit. Rules can differ by park and by season.
The Trash and Food-Safety Problem
A viral food trend that happens on a riverbank was always going to leave something behind. Korean outlets have pointed to plastic trays, vinyl bags, sauce cups and leftover fish and seasoning as the main headaches. Seoul city said it expanded recycling-separation bins at the Han River parks this year from two compartments to five.
What to do:
- Take everything home or sort it into the right bin. Our Korea trash sorting guide explains the system.
- Do not pour leftover broth or sauce on the ground.
- Keep fish cold with ice packs, and eat it soon after buying.
- Skip hwe-nic on hot days. If in doubt, choose a cooked picnic.
- Avoid raw fish if you are pregnant, immunocompromised, or unsure about shellfish allergies.

Frequently Asked Questions
What does 회크닉 mean? It combines 회 (raw fish, sashimi) and 피크닉 (picnic). It means eating takeaway sashimi at an outdoor picnic, usually beside the Han River.
Where do people buy the fish? Mostly Noryangjin Fish Market in Dongjak-gu, which is near both Yeouido Hangang Park and Nodeul Island. Some stalls have also begun offering pickup and group-order services.
How much does a hwe-nic cost? A seasonal sashimi platter for two was reported from around ₩65,000. With drinks and ramyeon, expect to spend somewhat more.
Is it safe to eat raw fish in a park? It can be, if the fish is fresh, kept cold and eaten soon after purchase. Korean advice is to use ice packs and avoid leaving fish in the sun. Avoid it on hot days.
Can tourists do this without speaking Korean? Yes. Point at the fish you want, say or show “포장” for takeaway, and ask the price before the fish is cut. Many stalls are used to foreign visitors, though language support varies.
Is it a lasting trend? Search interest rose sharply from a small base, and the weather will end the season soon. Whether it continues next spring will depend on whether the trash and queue problems are managed.
Fried chicken is not going anywhere on the Han River, but this autumn the mat next to yours might hold a tray of halibut instead. If you are in Seoul on a cool evening, a hwe-nic from Noryangjin is one of the most Korean ways to spend ₩30,000 or so a head, as long as you leave the riverbank cleaner than you found it.
